I am stuck at the phaaryl megalith Boss spawn on devourer roots

I am stuck on the map, the boss spawn on the roots and never come out.

Same thing happened to me just now. Terrain/Abilities caused by bosses stays even after their death. I got devourer early and some bosses either got stuck rendering them unable to move (I was still able to attack them). When 2 bosses spawned at the same time 1 spawned inside devourere's roots rendering me physically unable to either leave the map or kill the boss or getting killed. Had to log out now and wait for the map to time out so i can resume playing.
